NEOS Interfaces to FilMINT

FilMINT is based on the LP/NLP algorithm by Quesada and Grossmann implemented in
a branch-and-cut framework. It combines the MINTO branch-and-cut framework for MILP
with filterSQP, an active set solver, used to solve the nonlinear programs that
arise as subproblems in the algorithm. Through MINTO, we are able to exploit a range
of modern MILP features, such as enhanced branching and node selection rules, primal
heuristics, preprocessing, and cut generation routines.

Using the NEOS Server for FilMINT

The user must submit a model in
AMPL
format to solve a mixed integer nonlinearly constrained optimization problem.
Examples of models in AMPL format can be found in the
MacMINLP library.

The model is specified by a model file, and optionally,
a data file and a commands file.

If the command file is specified it must contain
the AMPL solve command.

The commands file can contain any AMPL command
or set
options for FilMINT .
Printing directed to standard out is returned
to the user with the output.
